------------------------------------
Summary: Improve the query cache heuristic to detect costly queries
Key: LUCENE-7050
URL: https://issues.apache.org/jira/browse/LUCENE-7050
Project: Lucene - Core
Issue Type: Improvement
Reporter: Adrien Grand
Assignee: Adrien Grand
Priority: Minor
Term queries, phrase queries and their combinations through boolean queries
should not be cached too agressively since they can efficiently make use of
skip lists. However we also have a number of queries that in practice need to
visit all matches anyway like PrefixQuery, TermsQuery, PointInSetQuery,
PointRangeQuery, so caching them more agressively can help avoid computing all
documents that match in the whole index again and again.
